Different song format; Duplicate song entries

[InTheFlow]

Whenever I convert an .ape file to .mp3 using media monkey without deleting the original file, it makes a duplicate entry of the song in the library.

This happens even if I tell MM to create the MP3 file in a directory other than the one monitored by file monitor.

Is there a way to turn that off somehow? The only thing I've found that might help is the 'analyze tracks for duplicates' option under the library.

Thanks.
